As the distance between the message source and designated destination increases, accurate transmission becomes increasingly more risky.
Data communication systems are designed with transmission speed and capacity to meet the timeliness and volume needs of defined users. Nonetheless, data delivery speed and capacity are determined by the choice of equipment and channels, modulation technique, transmission mode, as well as transmission direction.
As discussed in Computer Hardware Risks – Part II, a failure in an electronic element of an information technology (IT) configuration can cause an error by affecting the frequency, timing, strength, or shape of an electrical pulse utilized to convey datum.
